Question

Which statement correctly compares the pH of water to that of other substances?

a: The pH of water increases as its temperature increases, while other substances have a stable pH.
b: The pH of water is neutral; it is higher than the pH of acids and lower than pH of bases
c: Water contains more hydrogen ions than most other substances, giving it a higher pH.
d: Water is neutral and has a pH of 0; acids have a pH greater than 0 and bases have a pH less than 0

Answer 1

b: The pH of water is neutral; it is higher than the pH of acids and lower than pH of bases

Answer 2

The right answer is B.

The abbreviation pH refers to the notion of hydrogen potential. The pH has since become an indicator of acid solutions - when the pH is below 7 - or alkaline solution - when the pH is above 7 - of a solution. A neutral medium displays a pH of 7. This is the case of pure water at 25 ° C.
